hello shootie
i love what you ask becouse its somthing i was fighting my self for some time!

i play with Udinesee now in my 3rd year and since italy leage are so differnt from england i had the same struggled againt no wings style of play
well after i try many things i found out and its a bit funny, the best tactic against this is actuly the same tactic, 4312
there is no way you can play defence against this tactic or even counter style becouse this tactic use 80% max abilty in offence, the full backs have alot more space and they put presure close to the helf, so if you have wingrs you simple cant pass them the ball and if you do they will lose it to the full backs.
with Fiorentina you can easly win 90% of your games useing this tactic, and to be true this tactic is so strong that when you finsh your games you will see that you have 2 times more chances then the other team.
so this how you shold do it to apply the tactic
set 4312
Pilosophy: Balance
Strategy: Attack (its also very strong as defence)
Pass Style: Shorter
Creative: More
Clossing: Press More
Tackling: Default
Marking: Zonal
Crossing: Default
Roaming: Default
on the 3 MC make the left and right going to attack and make sure they have good off the ball and work rate
the MC in the center will play as ball wining defence and he will orgnize your attacks from the back so make sure to put one with hi jumping and fair strenght
the 2 ST are both attack and your AM is on support
this probly the most easy and strong tactic in the game (for top teams)
enjoy (sorry for my english)
